What does this Trump tweet mean?

[Bitek]

When the only other candidate was a child sex trafficking murderer who sold all of America's uranium to Russia and cheated that guy they were never going to vote for anyway, what choice did they have?

True dat.

However I would remind conservatives that they had 19 candidates to choose from, and they chose Trump.

Dems only had a choice between the child sex pimp and the dottering communist.

Even then they were more stable choices than Trumpo.
